ROBERT A. ANDES, OF MARCA, ILLINOIS.

HARROW-HINGE.

Application filed May 17, 1919.

To all whom t may-concern:

Be it known that I, ROBERT A. ANDES, a citizen of the United States, and a resident of Marca, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in I-larrow- Hinges, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates primarily to hinges for use in connection with the beam to which the different sections of a multi-section harrow are attached.

One object of my invention is to so arrange and construct the device that when used in connection with a harrow of comparatively great width, the end sections of the harrow may be folded over the center section or sections so that the harrow may be easily moved from place to place through the ordinary gates used on the farm.

Another object of my invention is to so construct and arrange the parts that when in use the end sections of the harrow may, to a limited extent, follow the contour of the ground, the device acting in a measure as an equalizer, to equalize the action of the various sections and assist in leveling the ground, a movement limit being provided to prevent the end sections from moving downward to a position which might cause the harrow to become locked or overturned.

Another object of my invention is to provide a movement limit whereby the end sections will be held from moving downward upon the center sections to an extent which might damage the adjusting levers, when the end sections are folded over into transportation position.

Other objects of my invention will appear and be Ydescribed in the specification.

The novelty of my invention will be hereinafter more fully set forth and specifically pointed out in the claims.

In the accompanying drawing:

Figure l is a plan View of a four section harrow showing my device attached thereto the harrow being in operative position.

Fig. 2 is a front view of one of the hinges showing the proper position of the parts by dotted lines when one of l the end sections is folded back for transportation.

Fig. 3 is a plan view of Fig. 2.

The same numerals of reference are used to indicate identical parts in all the figures.

Specification of Letters Patent.

Patented Julie 8, 1920.

Serial No. 297,816.

In the drawing 1 represents the usual harrow section which is connected to the beam 2 after the usual or any suitable manner.

lIn the ordinary form of construction the beam 2 is integral from end to end and in the ordinary 3, 4 or 5 section harrow, when it is desired to move from field to field or votherwise move the harrow so to require passing through a gate, it is necessary to disconnect at least some of the sections from the beam so that the harrow may be handled. By the use of my hinge, I am enabled to so divide the beam that its sections may be turned back upon one another so that the width of the harrow is reduced, and to that end, the beam 2 is cut at the proper points and the sections hinged together as will now be described.

By referring to Figs. 2 and 3, the construction and arrangement of the parts of the hinge may be more readily understood. Each hinge comprises a member 3 which is adapted to be bolted as at t or otherwise suitably secured to one of the sections of the beam 2, the member 3 carrying a finger 5 and a hook 6, the latter being preferably formed as an extension to the pin which acts as the pivot for the hinge.

The member 7 of the hinge is provided with an eye which is adapted to pass over the hook 6, the eye being offset as shown in Fig. 8 so that the surface which lies against the section of the beam 2 is in line with the corresponding surface of the member' 3. The member 7 is secured in place in a manner similar to that employed for the section 3.

Each of the sections 3 and 7 is provided with ears 8 which embrace the upper and lower surfaces of the sections of the beam, adjacent the ends of these sections in such manner that the beams are held against splitting at their ends and to further assist in properly maintaining the parts in position, a. series of projections 9 are provided, these projections being on the surface of the members 3 and 7 which contact with the sections of the beam 2, the projections 9 being preferably in the form of small pyramids which are adapted to be forced into the beams and thereby assist in holding the parts in proper position.

The finger 5 acts as a movement limit for the member 7 with relation to the member 3 to the end that the end sections of the harrow may assume a lower position than the center sections, the finger acting to prevent a downward movement of the end sections to an extent which might cause these sections to buckle and overturn the harrow, the finger 5 being preferably arranged to come in contact with the offset portion of the member 7 which carries the eye 8.

The dotted lines of Fig. 2 show the position of the member 7 and one section of the beam 2 when the harrow is folded for movement through agate. In this position the offset portion of the member 7 comes in contact with the portion of the member 3 which carries the hook Gand supports the member 7 in the position shown thus affording a movement limit to prevent the harrow sections from injuring one another by coming in contact.

As shown inFig. l the harrow is provided with a dra-ft chain 10 which is ordinarily attached to the beam near its ends, the hooks 6 being provided forthe purpose of engaging an intermediate portion ofthe draft chain so that when the end sections are raised, the draft chains will extend forward from the same plane they formerly occupied to the end that after the end sections are raised and the chains engaged by the hooks, there will be no tendency for the harrow to be overturned when being moved from place to place. Y

Having thus fully described my invention, I claim:

l. In a harrow hinge the combination kof a sectional draf-t beam, a connection between the adjacent ends Vof the sections of said -beam whereby the width of the harrow may be reduced, a movement limit permitting a comparatively small downward angular position'ofone section-ofy the draft beam with relation to the other, and a movement limit permitting a comparatively large upward angular movement of one section of the draft bea-m with another.

V2. In a halrrow hinge the combination of a pair of hinge members adapted to be secured to adjacent ends of asectional draft beam, a hook carried by one of said members and engaging the other thereof to form its pivot and for engaging'. a ldraft member,

Vand a movement limit carried by one of said hinge members for limiting the movement of the other. i

3. In a harrow hinge the combination of a pair of hinge members adapted to be secured to adjacent ends of a beam, ears car,- ried by .each member rfor engagement with the faces of the draft beam sections, and movement limits carried bythe hinge sections for limiting the movement of .one thereof .with relation tothe other.

4. In a' harrow hinge theV .combination of a vpair of. hinge members adapted to be secured to adjacent .ends of-asectional draft beam, ears carried by each memberfor engagemcntfwith the faces of the draft beam sections, spurs carried by each section for engaging the section of the draft beam, a pivotal connection between the hin-ge sections and a movement limit carried byrone of said hinge sections for engagement with the other.
